By using planarchiral [2.2]paracyclophane‐containing N,O‐chelating ligands for tantalum‐catalyzedhydroaminoalkylation, one of the most versatile catalytic systems for this reaction to date was obtained. Convenient Csp3−Csp3 bond formation of amines with terminal and internal alkenes was enabled by the same in situ synthesized catalytic system of [2.2]paracyclophane‐basedpyridonates and Ta(CH2TMS)3Cl2

The design and synthesis of a mixed 2-pyridonate-Ta(NMe2)3Cl complex for the direct C-H alkylation adjacent to nitrogen in unprotected secondary amines are reported. The hydroaminoalkylation of sterically demanding internal alkenes gives the direct, catalytic formation of C(sp(3))-C(sp(3)) bonds. Substrate scope investigations reveal key strategies for further catalyst development efforts in this 100%
hydroaminoalkylation of terminal alkenes, 1,3‐dienes, or styrenes allows a direct and highly atom efficient (100 %) synthesis of amines which can result in the formation of two regioisomers, the linear and the branched product. We present a new titanium catalyst with 2,6‐bis(phenylamino)pyridinato ligands for intermolecular hydroaminoalkylation reactions of styrenes and 1‐phenyl‐1,3‐butadienes that delivers the
We report a Rh‐catalyzed hydroaminomethylation reaction of terminal alkenes in glycerol that proceeds efficiently under mild conditions to produce the corresponding amines in relatively high selectivity towards linear amines, moderate to excellent yields by using a low catalyst loading (1 mol % [Rh], 2 mol % phosphine) and relative low pressure (H2/CO, 1:1, total pressure 10 bar).
